It's been awhile since I've bought a new desktop so last week I pushed the button on a new iMac. It arrives Wed. I also bought an ext SSD for my boot and documents. I'm going to skip migration assistant and go with a fresh copy of OS X and my apps. To make use of the time I was thinking about installing the OS now so it would be ready to go Wed. Is it possible to do this on a different Mac or will doing so mean some hardware enablers won't get installed or activated?
